HOW TO SET UP YOUR UNIT
Location of the Air Compressor
GROUNDING INSTRUCTIONS (FIG. 1)
The portable air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug (A).
Do not modify the plug provided. If it does not fit the available outlet, a correct outlet should be installed by a qualified electrician.

EXTENSION CORDS
If an extension cord must be used, be sure it is:
NOTICE: Risk of Property Damage. The use of an undersized extension cord will cause voltage to drop resulting in power loss to the motor and overheating. Instead of using an extension cord, increase the working reach of the air hose by attaching another length of hose to its end. Attach additional lengths of hose as needed.
VOLTAGE AND CIRCUIT PROTECTION
Refer to the Specification Chart for the voltage and minimum branch circuit requirements.
Warning: Risk of Overheating. Certain air compressors can be operated on a 15 amp circuit if the following conditions are met.
If any of the above conditions cannot be met, or if operation of the compressor repeatedly causes interruption of the power, it may be necessary to operate it from a 20 amp circuit. It is not necessary to change the cord set.
KNOW YOUR AIR COMPRESSOR
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference.
DESCRIPTION OF OPERATION (FIG. 2–4)
Become familiar with these controls before operating the unit.
On(I)/Off(O) Switch (D): Place this switch in the On (I) position to provide automatic power to the pressure switch and Off (O) to remove power at the end of each use.
Pressure Switch (not shown): The pressure switch automatically starts the motor when the air tank pressure drops below the factory set "cut-in" pressure. It stops the motor when the air tank pressure reaches the factory set "cut-out" pressure.
Safety Valve (H): If the pressure switch does not shut off the air compressor at its "cutout" pressure setting, the safety valve will protect against high pressure by "popping out" at its factory set pressure (slightly higher than the pressure switch "cut-out" setting).
Tank Pressure Gauge (I): The tank pressure gauge indicates the reserve air pressure in the tank.
Outlet Pressure Gauge (E): The outlet pressure gauge indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure.
Regulator (G): Controls the air pressure shown on the outlet pressure gauge. Turn regulator knob clockwise to increase pressure and counterclockwise to decrease pressure.
Cooling System (not shown): This compressor contains an advanced design cooling system. At the heart of this cooling system is an engineered fan. It is perfectly normal for this fan to blow air through the vent holes in large amounts. You know that the cooling system is working when air is being expelled.
Air Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet.
Drain Valve (K): The drain valve is located at the base of the air tank and is used to drain condensation at the end of each use.
Check Valve (M): When the air compressor is operating, the check valve is "open", allowing compressed air to enter the air tank. When the air compressor reaches "cut-out" pressure, the check valve "closes", allowing air pressure to remain inside the air tank.
Motor Overload Protector (not shown): The motor has a thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart:
Quick-Connect Body (F): The quick connect body accepts industrial quick connect plugs. The two quick connect bodies allow the use of two tools at the same time.
HOW TO USE YOUR UNIT (FIG. 2)
How to Stop
Before Starting
Do not operate this unit until you read this instruction manual for safety, operation and maintenance instructions.
Before Each Start-Up
NOTE: The hose or accessory will require a quick connect plug if the air outlet is equipped with a quick connect body (F).
Warning:
NOTICE: Risk of property damage. Compressed air from the unit may contain water condensation and oil mist. Do not spray unfiltered air at an item that could be damaged by moisture. Some air tools and accessories may require filtered air. Read the instructions for the air tools and accessories.
How to Start
1. Set the On/Off switch (D) to "On" and allow tank pressure to build. Motor will stop when tank pressure reaches "cut-out" pressure.
2. Turn regulator knob (G) clockwise to increase pressure and stop when desired pressure is reached.
Warning: Risk of unsafe operation. If any unusual noise or vibration is noticed, stop the compressor immediately and have it checked by a trained service technician.
The compressor is ready for use.

CUSTOMER RESPONSIBILITIES

Warning:
Before starting compressor, pull the ring on the safety valve (H) to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve
TO DRAIN TANK (FIG. 2, 3)
Warning: Risk of Unsafe Operation. Air tanks contain high pressure air. Keep face and other body parts away from outlet of drain. Use ANSI Z87.1 eye protection (CAN/CSA Z94.3) when draining as debris can be kicked up into face.
Warning: Risk from noise. Always wear proper hearing protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.
NOTE: All compressed air systems generate condensate that accumulates in any drain point (e.g., tanks, filter, aftercoolers, dryers). This condensate contains lubricating oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations.
Warning: Risk of Bursting. Water will condense in the air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture.
NOTICE: Risk of Property Damage. Drain water from air tank may contain oil and rust which can cause stains.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, the reinstalled.
